Method and apparatus for analyzing and/or comparing handwritten and/or biometric samples
First Claim
1. A computer based method for determining whether biometric samples are from a same source, comprising the steps of:
- comparing a first biometric sample with a second biometric sample with a general purpose computer, wherein said first and second biometric samples form at least one cluster of at least one vector based on feature similarities between said first and second biometric samples; and
, determining by means of said general purpose computer whether said first and second biometric samples are from said same source, wherein the first biometric sample and the second biometric sample are handwriting samples and said at least one cluster is a composite based on a model for measuring the distance between a first binary feature vector and a second binary feature vector and wherein the accuracy of said model is measured by calculations involving features selected from the group consisting of micro-features, macro-features and a combination of micro- and macro-features.

Abstract
A computer based method of biometric analysis which compares a first vector from a first biometric sample with a second vector from a second biometric sample. The vectors have at least one biometric feature. A method which compares two biometric samples. The samples form at least one cluster of at least one vector based on feature similarities between the samples. An apparatus incorporating a means for performing the method taught herein. A computer-readable medium and a propagated computer data signal transmitted via a propagation medium, with instructions which when executed by a processor, carry out the method of the present invention. A method of handwriting analysis which calculates a first metric from a first vector having at least one feature from a sample, calculates a second metric from a second vector having at least one feature from a second sample, and calculates the distance in two-dimensional feature space between metrics.
